Section XV, Note 6 aHTSUS, defines the term Waste and Scrap as "Metal waste and scrap from the manufacture or mechanical working of metals, and metal goods definitely not usable as such because of breakage, cutting-up, wear or other reasons.

Protestant's reference to alloys of the base metals of chapter 81 is misplaced here because the term "alloys" includes sintered mixtures of metal powders but excludes cermets. They can also dissolve and actively take part in physiological processes, for example, whena material chemically similar to bone structure, can integrate and help bone grow into it. The United States Air Force saw potential in the material technology and became one of the principal sponsors for various research programs in the Tungsten Carbide - Cobalt Cermets.

The merchandise in issue is a carbide which is a compound not a base metal. Metallurgical Concepts, "Creep and Stress Rupture". Composites ofan emerging class of ternary or with or have been studied since 2006 as high-value materials exhibiting favourable properties of ceramics in terms of hardness and compressive strength alongside ductility and fracture toughness typically associated with metals.

They saw a use for this for the high-temperature sections of new as well as high temperature turbine blades. Customs believes the notes should always be consulted. These include the development of lightweight ceramic projectile-proof armor for soldiers and also.

Cermets are also used in as a material for fillings and prostheses.

HQ 951642

The notes state further that among the most important cermets are those obtained by sintering tungsten carbide with cobalt. HQ 951642 - Cermet Waste and Scrap; Tungsten Carbide Waste and Scrap; Broken Drill Bits, Mill Cutters, Inserts; Headings 8101.

The multiaxial ball was tough metal ball but was eventually replaced with a longer-lasting ceramic ball. He then cites item 629. This reduced the roughening associated with the metal Tungsten Carbide - Cobalt Cermets against the plastic lining of the artificial hip socket.

The merchandise in issue conforms precisely to this description. Because of the high-temperature seal, ceramic tubes withstand higher temperatures than glass tubes. Ceramic tubes can be outgassed at higher temperatures. ISSUE: Whether the broken end pieces are cermets for tariff purposes. The merchandise was entered under subheadingHarmonized Tariff Schedule of the United States HTSUSa provision for other tungsten waste and scrap.
